Explanation

Vitamin A is essential for the production of rhodopsin, the visual pigment in the retina that allows us to see in low light conditions.

Explanation

• Enzymes are biological molecules made up of proteins, which catalyze chemical reactions, speeding up metabolic processes in living organisms.
• Proteins provide the structure and active site for enzymes to bind substrates and facilitate chemical reactions.

Explanation

Taxonomy is the science of classification, naming, and identifying organisms.

Including animals, plants, fungi, and microorganisms.

It aims to group living things into categories that reflect their evolutionary relationships and shared characteristics.

Explanation

All species are given scientific names, also known as binomial nomenclature or Latin names.

This system was developed by Carolus Linnaeus.

It is used universally by biologists and scientists to identify and classify species.

Explanation

G is the gravitational constant, also known as the universal gravitational constant.

It is a fundamental constant of nature that describes the strength of gravitational attraction between objects.

The currently accepted numerical value of G is 6.673 × 10^-11 Nm^2 kg^-2.

Explanation

Lumen refers to the empty space inside dead cells of xylem vessels, which are arranged vertically and form the vascular tissue in plants.

The lumen provides a pathway for water and mineral transport from roots to leaves.

Explanation

Transpiration is the process by which plants lose internal water in the form of water vapor through aerial parts such as leaves, stems, and flowers.

This process occurs mainly through small openings called stomata.

Explanation

The breakdown of food molecules to release energy is called cellular respiration.

This process involves breaking down glucose and other molecules in the presence of oxygen to produce energy in the form of ATP (adenosine triphosphate).

Cellular respiration occurs in the mitochondria of cells.

Explanation

The centromere is the region where the two chromatids (sister chromatids) are attached to each other.

It serves as a constricted region that holds the chromatids together until they separate during cell division.

Explanation

Once you have the data, you may need to perform mathematical analysis.

It involves using statistical and mathematical techniques to interpret and draw conclusions from the data.
